Laura Langston, MOT, OTR/L

Occupational Therapist & Director of Therapy Services

It’s me…Laura Langston. I am the owner and Director of Therapy Services at Langston Pediatric Therapy. I graduated from Carthage College in Kenosha, WI in 2000, and completed a Master’s Program in Occupational Therapy at Midwestern University in 2002. Soon after graduating (or maybe even before), I had a dream of opening an amazing clinic focused on children and their families, where they could learn and develop. My dream started to turn into reality when I was asked by a parent of a child I saw at school to continue therapy over the summer. I agreed, and with the help of one single parent, who saw the potential my services could have on her son, I learned the winding roads of insurance billing. Soon, through word of mouth, more and more families were seeking my services.  On December 28, 2010, Langston Pediatric Therapy opened its doors!! It’s hard to believe it has been almost 10 years ago that this journey officially started. I am beyond thankful for my amazingly supportive husband, 2 beautiful boys, many wonderful therapists who inspire me every day with their enthusiasm and passion to help children, and the countless kids and families that have found their way into my heart forever!  I sincerely thank each and every one of you for allowing me to be a part of your story.

My specialty is Sensory Integration. This is what I am most passionate about, and I am inspired by Dr. Jean Ayres, the developer of Sensory Integration Theory, to reach as many children as I can. I also enjoy working with children who have difficulties with motor planning, handwriting, oculomotor dysfunction, and other developmental delays. I am excited to be a part of this community to develop a relationship with each and every one of you who look for our support.

Welcome to Langston Pediatric Therapy!!!

Mary Cassady, COTA/L

Occupational Therapy Assistant

Hey there! My name is Mary Cassady, and I am a Certified Occupational Therapy Assistant. I graduated with my Associates Degree in 2022 and moved from Michigan in early 2023. When I am not working I stay busy with my puppy Otto and traveling to see family. I went into OT with the goal to help kids reach their full potential and live life to the fullest! I am so excited to start my journey as a COTA with Langston Pediatric Therapy. I look forward to learning and growing with my patients!


Wendy Emma, COTA/L

Occupational Therapy Assistant

My name is Wendy Emma, and I am a certified occupational therapy assistant.  I have worked for Langston Pediatric Therapy since 2010 when the doors first opened!  Upon graduating in 2000, I worked full-time as a hand therapist for a number of years. When I moved to the Sandwich area, I was working at an outpatient facility part-time, and the school settings part-time. It was during this time that I feel I found my niche. I continue to work in the schools full-time, but also enjoy working with Laura in the evenings on a part-time basis. I appreciate the diversity that occupational therapy has to offer.

I live in Sandwich with my husband, Joe, and have three beautiful kids! We live on a small farm, and have a menagerie of pets including horses, sheep, 2 cats, 2 dogs, 50+ chickens, 2 peacocks, and whatever else manages to get into our barn!

I look forward to getting to know you!

Nicole Kaminsky, MHS, CCC-SLP/L

Speech-Language Pathologist

Hi! I am Nicole Kaminsky, a Speech-Language Pathologist at Langston Pediatric Therapy. I have been a part of this wonderful Langston Pediatric family since 2014. I graduated with my bachelors from Elmhurst College and went on to obtain my masters at Governors State University. I am a member of Illinois Speech-Language Hearing Association (ISHA) and American Speech-Language Hearing Association (ASHA). In my years as an SLP, I have had the opportunity to work with a variety of ages and disorders. I have a passion for working with families to best support their child’s communication needs. I truly believe speech-language therapy should be fun, functional, and family oriented. I am truly blessed to be a part of this amazing career!

Sarah Gallichio M.S., CF-SLP

Speech and Language Pathologist

Hi! I am Sarah Gallichio, a Speech-Language Pathologist at Langston Pediatric Therapy. I have been serving children as member of the Langston Pediatric family since 2020. I graduated with my bachelors from Augustana College in 2018 and went on to obtain my masters at St. Ambrose University where I graduated in 2020. My biggest goal for my speech room is to create a language enriched environment that will facilitate learning, appreciate each child’s individual needs, and ultimately be a place for your child to have fun. I want each child I work with to enjoy speech-language therapy and to look forward to improving their skills. Communication is a right that everyone deserves access to. It is my mission to ensure that my clients and their families have access to communication in order to successfully exchange their wants, needs, thoughts, and ideas. I am so grateful for the opportunities that Langston has given me and I cannot wait to explore further opportunities with your family!

Heather Groetzenbach, CCC-SLP/L

Speech Language Pathologist

Hi! I’m Heather Groetzenbach, and I am a Speech-Language Pathologist at Langston Pediatric Therapy. I began my vocational journey into speech 7 years ago, when Langston welcomed me as a clinical student during my graduate program with Governor’s State University. Following my graduation in 2017, I was hired onto the amazing Langston team part-time, while also working in adult rehabilitation. Life carried me to Arizona for the past several years where I continued to work in a variety of settings including acute care, rehabilitation, and outpatient pediatrics (but I definitely squeezed in some hiking and adventures while there!). I recently returned to Illinois and am blessed to be welcomed back to the Langston family once again. I cannot emphasize enough my gratitude and joy for working with such a mighty group of therapists.

I consider myself to be adventurous, and I definitely believe in thinking outside of the box when it comes to the therapeutic approach. There is no one-size-fits-all method, as all of our little learners are vastly different. I am amazed every day by the fortitude and resilience of children, and believe firmly in capitalizing on ability over disability. It is my goal to help your child to experience speech and language acquisition in a playful, comfortable, and safe space. The learning journey isn’t always easy for our kids, but it should ultimately feel rewarding and fun. Thank you for allowing me to be a part of your child’s journey! I look forward to sharing my skills with you and your family. 


Ashley McDermott, MHS, SLP

Speech and Language Pathologist

Hello! I am Ashley McDermott and I am a Speech Language Pathologist-CF at Langston Pediatric Therapy. I completed a clinical rotation at Langston during graduate school and I am so happy to be back! I received my bachelor’s degree from Saint Louis University in 2021 where I double majored in Communication Sciences, Disorders, and Psychology. I then went on to receive my master’s degree in Speech-Language Pathology from Elmhurst University in 2023. I have had a wide variety of clinical experiences within private practice, school, and acute care medical settings and have enjoyed treating both pediatric and adult populations. I have a special admiration for children because of their positive energy and willingness to learn and am especially interested in pediatric language, pediatric feeding, and AAC. My ultimate goal as a speech pathologist is to foster communicative independence and to strengthen functional speech/language skills using individualized, evidence-based methods that are fun and motivating for clients. I am so excited for the opportunity to work alongside the wonderful therapists at Langston and for the opportunity to work with your family!
